I think you need a bigger cooler before you will be able to reach the 200 mark with your specs, thats about the only thin missing now

Have a look at Dave Bakers site. There are all sorts of formulae and explanations to help you calculate your expected power from the
size of your inlet valves www.pumaracing.co.uk
Also lots of other excellent information including the many ways
a lot of so called experts are using absolute waffle to separate
you from your dough.

depends on who done the head work mate you can buy a head for ฃ500 that will flow worse than a standard one who did the work on the head ?
